ACL 5M7807H-STD Race Series Main Bearing Set

The ACL 5M7807H-STD is a part of the renowned Race Series, specifically designed for high-performance applications. These main bearings are crafted with a unique blend of design and metallurgy to meet the demands of drivers who push their engines to the limit. Built to endure higher RPM conditions, they provide a reliable foundation for those who seek both performance and durability.

Features:

  • High strength overlay plate with a reduced thickness, enhancing fatigue properties for better longevity.
  • Hardened steel backs on all rod bearings, ensuring improved support for the bearing lining and better retention in the housing.
  • Increased crush for enhanced bearing retention, keeping everything securely in place.
  • Elimination of flash plating on the back of the bearings, which aids in heat transfer and maximizes grip within the housing.
  • Increased eccentricity to counteract bore distortion at high RPM, facilitating the formation of hydrodynamic oil films.
  • 3/4 grooved main bearings designed to optimize load carrying surface area and improve oil flow to the conrod bearings.
